GEORGE E. I-EASKINS, OF MILFQRD, GONNECTICUT.

CATTLE-STANCI-IION.

Application filed May 6, 1914.

T all whom it may concern Be it known that I, GEORGE E. HAsKINs, a citizen of the United States, residing at the town of Milford, county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Cattle- Stanchions; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to certain new and useful improvements in cattle stanchions, and the primary object thereof is to provide an improved, simplified and effective means for automatically locking the movable bar of the stanchion in closed position.

In the drawings: Figure 1 is a front elevation of the invention; Fig. 2 is an enlarged top plan view of the locking device,

Fi 3 is a fra unentar' side elevation a :3 .i a partly in section showing the lock member in operatlve and lnoperative positions; F193. 1 is an enlarged detail perspective View of the lock member; Fig. 5 is a fragmentarv side elevation, partly broken away and 111 section, of a modlfied form of the invention; Fig. 6 1s fragmentary top plan view of one end of the stanchion; Fig. 7 is a section taken on the line 7-7 of Fig. 6; and Fig. 8 V

is a section taken on the line 88 of Fig. 7.

The stanchion consists of the upper and lower beams 1 and 2 which are pivoted to journals 3 and 4 the beams being connected by the rigid bar 0 and the pivoted bar 6, all of which parts are common to stanchions as at present constructed.

The upper beam 1 is bifurcated at 7 to receive the upper end of the movable bar 6 and is provided on its opposite sides with a pair of brackets 8 which are rigidly secured thereto by screws, bolts, or thelike, 9. The brackets 8 are provided with upper perforated lugs or extensions 10 which provide bearings that are 'ofiset inwardly so as to overlie the top faces of the bifurcations of Specification of Letters Patent.

Serial No. 836,793.

stop finger 15 which engage the under or bottom face of a stop 11 tha is formed on the corresponding ear 10, whereby the inward and downward movement of the lock member will be restricted as shown in Fig. 3 of the drawings. The inner vertical face of the stop 11 provides a stop which engages member 12 to limit the upward and outward movement thereof, as shown in dotted lines in Fig. 3.

The upper end of the bar 6 is formed with an inner cam face 16 which is for engagement with the depending vertical part 17 of the member 12 whereby the bar will raise the member 12 from the full to the dotted line position indicated in Fig. 3. The upper end of the bar 6 is also formed on its side opposite to the side which has cam 16 with a concaved part 18 which conformably receives a convex inner face 19 on the member 12, as shown in Fig. 1. A shoulder 20 is formed on the inner end of the member 12, to seat on the top edge of the bar 5, and a fin 'er engaging part 21, is also provided on the member 12, to enable same to be manually lifted to unlock bar 6 and allow the latter to be moved to open position.

in operation the look, when the bar is in inoperative position, occupies the full line position shown in Fig. 3, and when the bar 5 is moved to operative position the cam 16 of same will engage the face 17 of the lock and move same to the dotted line position shown in Fig. 3, whereupon the lock will gravitate to full line position as shown in Fig. 1, in which position its convex face will seat in the concave face of the bar 6 and hold the parts effectively locked, since in order to disengage the parts, the lock must be raised to the full line position, by engaging finger grip 21, so as to allow the top end of the bar 6 to pass beneath the lock. By the provision of the convex face 19 and the concave face 18, it will be evident that a large area of contact is afforded between the lock and bar 6, which regardless of the outward pressure exerted on the bar 6, will not injure, indent, or deface or mar the wood of which bar 6 is formed, since no sharp edges are present which can bite into the wood and thus in time make the lock have a loose fit, as is common in devices con structed prior to this invention. In addition, no springs are necessary to assist the ears. One of the ears 13 is formed with a look in its function, and accidental disengagement of the bar from the lock is prevented. i

As shown in Fig. 1 of the drawings, the lower beam 2, receives the lower end of bar 6, and has an inclined wall 22, against which the inner side of the bar 6 abuts and is accordingly restricted in its outward movement. The bar 6 is eccentrically pivoted at 23 in such manner that the bar at the lower end thereof will engage flat against wall 22, without the necessity of beveling'the lower end of the bar, as shown in dotted lines.

The beams are each preferably formed of a pair of spaced bars separated by a filler block 2 L, which block as shown in Fig. 5, may be provided with a hole 25, through which a bolt 26 passes and is engaged by a chain 27, which is attached to the overhead support. The lower beam 2, it will be understood, is also provided with similar securing means, not shown, the chains being an optional mode of securing or anchoring the stanchion, in lieu of the journals 3 and 4t shown in Fig. 1.

Bar 5, has a groove 28 into which projects a metal tongue 29 carried by a metal plate 80, the plate and tongue being formed of metal, and the tongue having beveled or wedge-shaped sides. The side edges of the bar 5, at the ends of the latter are-faced with metal plates 31, secured in position by bolts 32, which facing plates have cut-out portions that receive the tongues 29, the inclination of the sides of the tongues being less than that of the sides of the cut-out portions so as to provide a wedging action between the effected. Wear plates 35, are engaged with the bolt 33, so as to not allow the latter to bite into the wood. It will be understood,

tongues and the plates 31, when the bars comprising the beams are drawn together by the bolts 33. By this means the parts are rigidly and firmly connected. The beams and the plates 30 with tongues 29, are provided with a series of apertures 3i so as to enable the bar 5 to be moved toward the bar 6, whereby to allow of adjustment of the space between the bars 5 and (i. The facing plates '31, take-up any wear which impingement of the tongue 29 in the groove 28, of bar 5, would ordinarily cause, and in addi tion enable a metallic binding action. to be Copies of this patent may be obtained for that the structure described in connection with thebeam 1, and the upper end .of the bar 5, is duplicated between the lower end of the bar 5' and the lower beam 2.

2. In a cattle stanchion, a pivoted bar having an inner cam face and an outer concaved portion both at its upper end, a grav ity operated lock having a depending outer part to engage the cam face and a convex inner part to be conformably received in said concaved portion of the bar, and a shoulder extending outwardly from said convex part to seat upon the extreme upper end of thebar, and means tov limit the extent ofswinging movement of the lock."
